本文介绍了雷击对高层建筑的电磁场辐射的观测和分析。自1991年以来，对加拿大国家电视塔雷击的电磁场波形和电流波形进行了同步测量，提出了一种新的电磁场辐射计算模型。所提出的模型由雷电流传播和分布模型和电磁场辐射模型组成。根据在加拿大国家电视塔观测到的雷电流，所提出的模型计算出的电磁场与塔以北 2 公里处观测到的电磁场非常吻合。
This paper describes the observation and analysis of electromagnetic field radiation from lightning strokes to tall structures. Electromagnetic field waveforms and current waveforms of lightning strokes to the CN Tower have been simultaneously measured since 1991. A new calculation model of electromagnetic field radiation is proposed. The proposed model consists of the lightning current propagation and distribution model and the electromagnetic field radiation model. Electromagnetic fields calculated by the proposed model, based on the observed lightning current at the CN Tower, agree well with the observed fields at 2 km north of the tower.
